Nondisp commnt fx shaft of unsp tibia, 7thQ

This code describes a tibia shaft fracture that is broken into multiple pieces (comminuted) but remains in its normal anatomical alignment (nondisplaced). It specifically indicates that this is a follow-up encounter for an open fracture (where the bone broke through the skin) of type I or II, and the fracture is healing incorrectly, resulting in a malunion. The specific tibia involved is not documented.

Use this code for subsequent encounters when a patient with a previously treated open comminuted, nondisplaced fracture of the tibial shaft (type I or II) presents with evidence of malunion. This applies when the physician is actively managing the malunion, such as during follow-up appointments for assessment, imaging, or planning corrective procedures.

• Ensure documentation clearly specifies "malunion" and not just delayed healing or nonunion.
• Verify the original fracture was an open fracture type I or II, as this impacts the 7th character.
• Confirm the fracture is of the shaft and is comminuted and nondisplaced.
